My ds2 has been waking up every night for the past 3 nights at around 2am and walking into our room complaining of nightmares - "noises and flashing lights". I take him back to bed and as soon as his head hits the pillow the terrors come again. It takes ages to settle him. A friend mentioned that there are great bedtime story books that help restful sleep. Have got 'The Sandman' but has anyone else had experiences like this and found anything that helps?
